DESCRIPTION:
Mavituna Security has reported a weakness in Orchard, which can be
exploited by malicious people to conduct spoofing attacks.

Input passed via the "ReturnURL" parameter to Users/Account/LogOff is
not properly verified before being used to redirect users. This can be
exploited to redirect a user to an arbitrary website e.g. when a user
clicks a specially crafted link to the affected script hosted on a
trusted domain.

The weakness is reported in versions 1.0.x prior to 1.0.21, 1.1.x
prior to 1.1.31, 1.2.x prior to 1.2.42, and 1.3.x prior to 1.3.10.

SOLUTION:
Update to version 1.0.21, 1.1.31, 1.2.42, or 1.3.10.
